🔧 PRO TIP
The 2008 Scion XB uses a remote head key, meaning the transponder chip and the remote buttons are built into the same unit, not separate pieces. One fob does both jobs. The fob takes a CR2016, which is thinner than the CR2032 most people grab by habit. Wrong battery still fits and makes contact, but you'll get weak range and inconsistent starts before it finally gives out. The transponder side needs OBD programming to pair to the immobilizer. There's no ignition-turn self-program sequence on these, so a blank you buy online won't do anything until a tech with the right equipment registers it. If you're buying a spare fob from a third-party source, double-check the factory FCC ID on the back matches what came with your car before calling anyone out.

2008 Scion XB Remote Head Key Replacement - Fast, Affordable & Professional

Near Santee Lakes Area, a college student had been sitting on his parents' advice to get a spare key for his 2008 Scion XB for the better part of a year. Not because he didn't want one. Just because actually doing it meant driving out to a Toyota dealer, waiting around, and losing a morning he didn't have to spare with a noon class on the calendar.

He called me instead. I was already in Santee.

His original remote head key was worn but working, which made the job cleaner. I decoded the key blade at the lock, cut a fresh blade to match, and ran the programming sequence through the OBD port to register the new fob to the immobilizer. Tested the transponder, confirmed the engine started clean, then walked all three buttons until I was satisfied the remote side was synced up right.

Before I packed up, I showed him the CR2016 battery inside and how to swap it when range starts dropping. That part takes two minutes and costs almost nothing. He didn't know that battery was even in there.

He made his class. Didn't drive anywhere. The dealer had quoted him nearly double for a single key. He got two keys and never left the driveway.

Scion XB Mobile Service FAQ

Real costs, no dealer surprises

What battery does the 2008 Scion XB remote head key use?
CR2016. Not the thicker CR2032 that works in a lot of other fobs. The two look almost identical on a shelf, but the 2016 is noticeably thinner and they're not interchangeable in this fob. A 2032 won't seat right and you'll get intermittent contact issues that feel like a bigger problem than they are. Every remote head key I make for this car goes out with a fresh CR2016 already inside. If you just need a battery swap and your fob is otherwise in good shape, that's a quick DIY job. Pop the case, swap the cell, done. But if the remote still acts up after a fresh CR2016, the issue is elsewhere and you'll want a tech to look at it.
How do I know if a replacement fob I bought online will actually work for my 2008 XB?
How fast can you get to the Santee Lakes Area?
I have a spare fob for my 2008 XB but it won't start the car. The remote buttons work fine. What's going on?
Can I program a second key for my 2008 Scion XB myself at home?
